News Introduction:Tiger's eye (also called tiger eye) is a chatoyantgemstone that is usually a metamorphic rock that is a golden to red- brown colour, with a silky lustre. A member of the quartz group, it is a classic example ofpseudomorphous replacement by silica of fibrouscrocidolite (blue asbestos). An incompletely silicified blue variant is known as hawk's eye.

Manono Lithium-Tin Project, Democratic Republic of Congo

The Manono Lithium-Tin Project is an open-pit mining development in the Democratic Republic of Congo (DRC) in central Africa. It is estimated to be one of the largest lithium-rich LCT (lithium, caesium, tantalum) pegmatite deposits in the world. The Manono Lithium-Tin Project is located in the Democratic Republic of Congo.

Jul 29, 2013 Metamorphic rock from an Archean greenstone belt. Rocks in old terranes, such as the Archean greenstone belts of Canada, are often highly metamorphosed, while those of younger terranes may not be as altered depending on their geologic setting. Metamorphic rocks may often be labelled as “high grade” or “low grade metamorphic”.

1953). The other possibility is that these rocks represent higher-grade metamorphic facies, grading northward into more typical Belt rocks. Main rock types noted near the deposits include: 1) Hornblende gneiss and amphibolite, weakly foliated to coarsely gneissic; some banded or streaked. This is the most common wall rock of the deposits. 2) Light
